Hackers and Crackers are not one in the same (usually). Crackers break into systems, using tools, and dialers and stuff like that they got from a site. They don't care to understand what they're doing, or how it's doing it (usually like I said). Hackers create things, and care to learn, the net was built around hackers. Hackers can be crackers, but usually crackers can't be hackers.
